Abstract:
A dyeing apparatus comprises a dyeing vessel adapted to contain a dyeing liquid therein, a rotary shaft rotatably disposed as laterally suspended in the dyeing vessel, an impeller adapted to flow the dyeing liquid in a direction parallel to the rotary shaft, and a reel for permitting an article for dyeing to be rolled up thereon, the impeller and the reel being attached to the rotary shaft. The dyeing of the article rolled up on the reel is effected by causing the dyeing liquid to pass by permeation through the article from the lateral terminal part thereof by the rotation of the impeller. The rotary shaft may be rotated reversibly during the course of the dyeing.
Abstract:
The textile web (1) is guided through a relatively narrow shaft the limits of which are formed at least partially by the surface of rollers (2, 3). Nozzles (7), from which a treatment medium can be applied onto the textile web, are arranged in the curved sections (6, 6') of the shaft. Straight sections (8) between the rollers can be kept very short. The device is especially suitable for the treatment of tension-sensitive textile webs.
Abstract:
An apparatus for the continuous wet treatment of strand-like textile material wherein a treatment liquid flows countercurrent with respect to the direction of movement of the continuously conveyed textile material, and the textile material is squeezed at least once in a pipe or conduit system. A part of the treatment liquid which dams-up or collects in front of the squeezing location, is removed from the pipe system and reintroduced again into the pipe system at a location behind the dam-up region, considered with respect to the direction of flow of the treatment liquid.
Abstract:
An apparatus and method for providing an impregnation/rinsing of a web with fluid is disclosed wherein the web is repeatedly gently squeezed and allowed to open. A preforated conveyor belt carries the web within a longitudinal tank in which a series of squeeze rollers and a series of singular or cooperating rollers are arranged with the cooperating rollers being disposed intermediate the squeeze rollers. The web is carried by the conveyor belt beneath the first squeeze roller where the web is gently squeezed in a nip defined between the conveyor belt and the roller. The conveyor belt then carries the web above a cooperating roller. After the web has been gently squeezed, it is allowed to absorb the fluid in the tank without restraint until the web is gently squeezed again between the conveyor belt and the next squeeze roller. The steps of squeezing and absorbing are repeated throughout the longitudinal tank. Fluid is supplied to the longitudinal tank by one or more orifices which receive fluid from either a collection tank provided beneath the conveyor belt and longitudinal tank and/or from a supply of fresh fluid. The fluid in the tank typically travels in a path which is opposed to the general direction of travel of the web within the tank, especially when the apparatus is used as a rinser.
Abstract:
Process for reducing the "frosting effect" in the dyeing of textile fabrics made of staple fibers according to a continuous operation with intermediate drying, which comprises flattening the fiber ends protruding from the material web, between impregnating and drying the textile material, by the action of mechanical means onto the surface of the material web and holding them tight to the web surface by ironing, and device for carrying out the said process.
Abstract:
In a heat fulling and water washing apparatus hot fluid is injected onto both surfaces of cloth from hot fluid injection nozzles being placed in upper and lower rows to sandwich the passing path of the cloth in such manner that the positions of nozzles in the upper row alternate with those of nozzles in the lower row, in a process of passing cloth through an opening between upper and lower net conveyors in such state as immersing the cloth in cleaning liquid, so that both cleansing effect and fulling effect are given to the cloth.
